You can see the output is in six columns.
The first column is CPU-id, the second is PID, third is the time since boot in
microseconds, fourth is the elapsed time since the previous action. The fifth
and sixth columns represent the action. The Tcl command or procedure name is
prefixed by an indicator reprenting what is happening. These may be ->
(procedure entry), <- (procedure return), > (command entry), or < (command
return).
As each action is taken, the fifth and sixth columns are indented by 2 spaces.
This shows which procedure or command is calling which.
If the output looks shuffled, check the CPU "C" and "TIME" columns, and
post sort based on TIME if necessary.
See Notes/ALLflow_notes.txt for important notes about reading flow outputs.
